Maritana Minerals (ASX:MRT) started a second-phase drilling program at its Burbanks project in Western Australia, according to a Thursday filing with the Australian bourse.
Drilling is designed to test and extend the inferred resource of the Burbanks Main and Birthday Gift lodes from the current depth of 250 meters to up to 450 meters below surface, the filing said.
The company expects completion of an updated mineral resource estimate in the middle of the year, per the filing.
